RE. DESIGN FAULT . - THE PROBLEM WITH THE GEARS IS THAT WHEN THE CLUTCH CASE IS REMOVED THE SHAFT PULLS OUT WITH IT ALONG WITH THE TWO RATCHET GEARS + 2 WASHER /SHIMS .THESE ARE THEN OFTEN ASSEMBLED INCORRECTLEY LEADING TO THE KICKSTART GEARS BEING MISSALIGNED AND NOT MAKING FULL CONTACT WITH EACHOTHER , LEADING TO GEAR TEETH BENDING + EVENTUALLY SNAPPING BITS OFF . EVERY BIKE I HAVE WORKED ON WITH CORRECTLY SPACED GEARS HAVE HAD NO PROBS . AND ALL DAMAGED GEARS WERE BECAUSE OF INCORRECT SPACING ON REASSEMBLY .

MONT/HONDA 200 + COTA 200 KICKSTART GEARS ARE THE SAME THRU 1980 - 1984 . ONLY CHANGED FOR 242/304/307/309/310 ALONG WITH KICKSTART SHAFT + KICKSTART LEVER . STILL AVAILABLE NEW FROM SPAIN + FRANCE

KICKSTART LEVER OR KICKSTART GEARS ?

TRY 5W OIL IN DAMPER SIDE , USE DAMPING ADJUSTER FULLY ONE WAY -ve THEN FULLY ONE WAY +ve TO SEE IF YOU HAVE ADEQUATE DAMPING ( OR ANY DAMPING WITH 5W OIL) . IF NONE DRAIN OUT AND FILL WITH 20W AND PUT 5W IN SPRING SIDE

JUST SEEN YOUR OTHER POST , FILL USING 5W OIL IN DAMPER SIDE ( ONLY ) FIRST IF NO DAMPING DRAIN + TRY 20W + PUT 5W IN SPRING SIDE

IN 93 HAND BOOK IT SAYS 260cc BOTH LEGS ,BUT MENTIONS 2 X DIFFERENT GRADES OF OIL 5W + 20W . WOULD THINK 5W FOR DAMPER 20W FOR SPRING SIDE IF THESE RUN SPRING IN ONE SIDE ONLY . IF DAMPER RODS IN BOTH FORKS USE 5W IN EACH .

drain oil . lay bike on its side + remove clutch case while pressing kickstart shaft in towards engine with finger ( if you dont case might pull shaft out of position + bits will fall off). remove complete clutch (1 x centre bolt) + use 3 legged puller to remove . look at long pivoting arm with teeth that moves small toothed wheel . under this arm is either a solid or bushed small post that keeps arm against wheel , remove + rotate or make new slightly larger bush to take up any movement between toothed arm + toothed wheel . probably safer bet to remove the bolt on piece (three small bolts) to press / knock out post , but beware of shims + 2x small springs + sliding pieces

STEEL TUBE OR BAR TURNED DOWN TO FIT INSIDE BEARING HOUSING (GOOD TIGHT FIT) AND THEN WELD HOLES UP . REMOVE STEEL BAR + FILE /DRESS OUTSIDE OF SWINGARM . OPPOSITE APPLIES FOR STEEL SWINGARMS (ALLOY BAR INSIDE BEARING HOUSING + WELD)
